Some parts of the Open Fuel Cell (OFC) aren’t readily available but can be easily made with basic tools and materials. These include the membrane electrode assembly (MEA), gaskets, flow fields, and end plates. The following sections explain their functions and simple manufacturing processes.
Membrane Electrode Assembly (MEA)
The Membrane Electrode Assembly (MEA) is the central component of every PEMFC and has to fulfill a variety of different requirements. As a mechanical barrier
Flow Field and Current Collector
This post will help you understand why you’d need flow fields and how to make them yourself from off-the-shelf printed circuit boards (PCBs). Table of
Sealings
Sealings are used to prevent leaking of gases. Three types of sealing elements are used, with the most important being the flexible flat sealing element. The material used in the FDM-3D-printing process is the “Filaflex 70A” from the manufacturer “Recreus”, which is a highly flexible material.
